I know I definitely have the Aurora junk and I am sure there are others. Here is my HiJackThis log. Thank you in advance:

Good call by to post the HijackThis output — the pattern described in the thread (modified shell/startup settings, unexpected autoruns, unknown services and Winlogon/notify items) matches the mid-2000s “Aurora”/DirectRevenue-style PUP/adware: these families often hide multiple persistence points and can regenerate themselves unless every component is removed. Redmondmag reader tips. (redmondmag.com)

Containment first: isolate the PC from the network, then boot to Safe Mode (or Safe Mode with Networking when a trusted tool must update). Run a current, offline scanner (Microsoft Safety Scanner / MSRT or an up-to-date AV) and then a second on-demand anti‑malware scanner; running multiple reputable tools sequentially catches different components. For deep startup cleanup, use a trusted autorun viewer to inspect and disable every suspicious autostart entry. Microsoft Safety ScannerSysinternals Autoruns. (learn.microsoft.com)

If infections persist, the removal is usually manual: stop the malicious services/processes, remove the offending autostarts and BHO/toolbar entries, and delete leftover files and registry keys (do this from Safe Mode). Community removal walkthroughs from the period show using HijackThis misc tools to delete NT services and then deleting files/folders in Safe Mode works for many cases — but manual registry edits require care and backups. If the infection reappears or critical system components are altered, a backup-and-reinstall is often faster and safer. Kephyr Aurora removal notesMajorGeeks removal thread. (kephyr.com)

Note on vendor tools: ‘s post points to a vendor/uninstall utility — such “self‑removers” exist and have worked for some users, but they come from the same ecosystem that produced the PUPs and should be treated with caution. Prefer well‑known, community‑trusted tools or manual removal steps; when in doubt, image/backup important data and perform a clean OS install. Redmondmag reader tips. (redmondmag.com)
